Stream Maintenance Program Renewal, CEQA, Permitting, and Mitigation

Horizon Water and Environment (Horizon) is developing permit renewals and CEQA compliance for the 2012 Stream Maintenance Program Update (SMP Update) for the Santa Clara Valley Water District (SCVWD). Under the SMP Update, routine channel maintenance activities including sediment removal, vegetation removal and thinning, and bank stabilization are performed annually to maintain conveyance capacity in county flood control channels and water supply canals.  The SMP has been operating under and EIR and program permits that were issued in 2002. The program has significantly evolved and the original program EIR and permit conditions do not adequately reflect the stream management goals of the District for the next twenty years.
Horizon is working closely with the District and regulatory agencies to incorporate lessons learned from the past ten years of program implementation to improve the program and its regulatory oversight.  Horizon is undertaking the following tasks:

  • Renewing regulatory programmatic permits for the next 10-year period.
  • Developing a creative and flexible mitigation program integrating on-site restoration activities with off-site watershed-based projects.
  • Conducting a new CEQA analysis of the District’s updated program and writing a certifiable Program EIR document.
  • Conducting outreach with regulatory staff from multiple agencies and jurisdictions.
  • Conducting several technical studies including wetlands inventory, sensitive species and habitat mapping, and cultural resources assessment to support the multiple permitting processes.
  • Helping the District revise their outdated SMP Manual.
